DS7428-CHI DS7428-CHI - Bosch Security Systems
1 | Overview
2 | Installation notes
DS7428-CHI Bus Extender Module
can extend using the DS7400 Series
MUX Bus. It can accommodate long
distance applications of the MUX
Bus up to 5 km in a single loop. The
DS7428-CHI requires a 12 VDC to
the power supply. All MUX devices
(including DS7457i, DS7432, DS3MX,
and DS6MX) can connect directly to
the DS7428-CHI bus.
These installation instructions assume
the control panel is installed and in
proper working condition.

Supported MUX Bus Modules includes
DS7432, DS7457/DS7457i, DS7460/
DS7460i, DS7465/DS7465i,DS3MX/
DS3MX-CHI, DS6MX/DS6MX-CHI.
Refer to the DS7400Xi-CHI Installation
Instructions for additional wiring
information.
CAUTION!
Failure to follow the
installation instructions in this
manual might result in damage
to the control panel.
Disconnect the power to the DS7400
Series Control Panel before you run
wires to connect the DS7428-CHI.
Install the DS7428-CHI in an enclosure
and in dry conditions.
•
Use only non-shielded and nontwisted cable (1.0 mm2 or above) for
the wiring in the MUX Bus (including
the Extend Distance Bus).
•
Without the DS7428-CHI, the longest
distance of the MUX Bus is 1.5 km.
•
A single loop MUX Bus can reach 5
km after installed with DS7428-CHI.
•
The wiring distance between
the first-level DS7428-CHI and
the DS7400Xi-CHI Control Panel
should be less than 1 m. The firstlevel DS7428-CHI can support Bus
diastance for 3.5km.
•
When the second-level DS7428CHI is installed, it can extend an
additional 1.5 km. The total distance
can reach 5 km of two levels of
DS7428-CHI.
•
In each DS7400Xi system when using
a DS7430 MUX Bus Driver, you can
only install maximum three pieces
of DS7428-CHI. In addition, you
can install maximum six pieces of
DS7428-CHI when you use DS7436
MUX Bus Driver.
•
The first-level DS7428-CHI should be
installed as close as to the DS7430/
DS7436 module, and connect the
input power. Use an independent
power source to support the remote
second-level DS7428-CHI (refer to
Figure 3.1 and Figure 3.2).
4 | Wire jumper instructions
•
•
Try to avoid running wires dispersedly.
DS7428-CHI has an isolation feature.
When the DS7428-CHI detects the MUX
bus fault, it isolates the loop.
Avoid connecting DS7428-CHI in
parallel. Using one first-level DS7428CHI can improve the reliability of
system.
When using the DS7428-CHI in a first
level connection, place the single loop
bus jumper wire to the “1ST” position
at P2.
